IAUA210N10S5N024AUMA1 Overview
What is an automotive-grade N-channel MOSFET? A metal-oxide-semiconductor field-effect transistor (MOSFET) is a voltage-controlled switch used to efficiently route and regulate power in electronic systems. An N-channel MOSFET conducts when a positive gate-source voltage exceeds its threshold; the OptiMOS 5 family from Infineon is the company's fifth-generation 100-200 V trench MOSFET platform, optimized for ultra-low RDS(on) per unit silicon area. In the broader taxonomy, it belongs to: power MOSFET -> discrete semiconductor -> power management component -> semiconductor device. Automotive-grade (AEC-Q101) variants are individually screened for temperature, vibration, and reliability stress demanded by 12 V, 24 V, and 48 V vehicle electrical systems.
Key differentiating specifications include a typical gate charge (Qg) tuned for low switching losses at high frequencies, an avalanche-rated single-pulse body diode, and a kelvin-source pin configuration in the PG-HSOF-5-4 package that separates the gate-drive return from the high-current source path. This decoupling reduces source-inductance ringing and improves switching performance in hard-switched topologies. The 100 V VDS rating provides substantial headroom above the 48 V automotive bus maximum, while the 2.4 mΩ RDS(on) minimizes conduction losses at high current, making the device well suited for high-power-density designs where PCB real estate is constrained.
Typical applications span automotive 48 V HVAC blowers and pumps, electronic power steering (EPS), brushless DC motor drive half-bridges, isolated DC-DC converter primary-side switches, hot-swap and OR-ing controllers in server/industrial 48 V rails, and high-current synchronous rectification stages. The AEC-Q101 qualification also makes the part attractive for off-road, agricultural, and construction vehicle electronics where environmental robustness is critical.
When designing with this device, attention to PCB layout, gate-drive loop inductance, and thermal management is essential. The exposed pad of the PG-HSOF-5-4 package must be soldered to a sufficiently large copper pour, and a low-inductance gate-drive return is required to realize the device's rated switching performance. Designers should also verify SOA at the intended DC-link voltage and continuous current, since the 210 A rating is junction-temperature limited and derates significantly with case temperature.

Typical Applications
IAUA210N10S5N024AUMA1 is suitable for 6 applications: 48V Automotive HVAC Blower Drive, Electronic Power Steering (EPS) Motor Drive, 48V-to-12V DC-DC Converter Primary Switch, Industrial 48V-80V BLDC Motor Drive, Hot-Swap / OR-ing Controller in 48V Telecom Rails, Solar String Inverter High-Side Switch.
48V Automotive HVAC Blower Drive
The IAUA210N10S5N024AUMA1's 100V VDS rating, 2.4 mΩ RDS(on), and 210A continuous drain current make it ideal for 48V HVAC blower motor half-bridge stages where the part switches at 20-50 kHz PWM with currents up to 80A per switch. The 100V breakdown provides sufficient margin above the 48V nominal bus voltage for load-dump and reverse-battery transients mandated by ISO 7637-2, while the kelvin-source pin in the PG-HSOF-5-4 (sTOLL) package minimizes gate-drive ringing, allowing cleaner switching edges and lower EMI emissions. AEC-Q101 qualification supports under-hood deployment where ambient temperatures exceed 105°C.

Electronic Power Steering (EPS) Motor Drive
In EPS systems, the IAUA210N10S5N024AUMA1 is typically used as the low-side synchronous rectifier in a three-phase BLDC inverter driving the steering assist motor at peak currents of 150-200A. The 2.4 mΩ RDS(on) minimizes conduction losses, reducing heatsink mass in the steering column assembly where space is severely constrained. The AEC-Q101 qualification and 175°C maximum junction temperature allow the part to operate reliably in the engine-bay environment. The kelvin-source pin enables clean switching at the high dI/dt required for low-torque-ripple steering feel.
Recommended
48V-to-12V DC-DC Converter Primary Switch
The IAUA210N10S5N024AUMA1 is well suited as the primary-side switch in a 48V-to-12V buck converter delivering 1-2 kW to the vehicle's 12V bus. The 100V VDS rating handles the 48V nominal plus transients, while the 2.4 mΩ RDS(on) and OptiMOS 5 low gate charge yield peak efficiencies above 96% at full load. Switching frequencies of 100-200 kHz are achievable, allowing a smaller magnetic and filter design. The PG-HSOF-5-4 sTOLL footprint provides a compact power stage suitable for integration into a transmission-mounted or battery-pack-mounted converter.
Recommended
Industrial 48V-80V BLDC Motor Drive
For industrial BLDC motor drives operating from 48V or 80V DC bus rails such as automated guided vehicles (AGVs), robotics, and conveyor systems, the IAUA210N10S5N024AUMA1 provides a robust, automotive-grade switching element. The 100V VDS rating gives margin above 80V nominal bus, the 210A current rating supports motors up to 5-10 kW, and the AEC-Q101 qualification exceeds typical industrial reliability standards. Industrial designers benefit from the same ultra-low 2.4 mΩ RDS(on) and kelvin-source layout used in automotive deployments, simplifying the bill of materials across platforms.
Recommended
Hot-Swap / OR-ing Controller in 48V Telecom Rails
In 48V telecom and datacenter bus OR-ing applications, the IAUA210N10S5N024AUMA1's 100V VDS rating, 210A current capability, and ultra-low 2.4 mΩ RDS(on) make it suitable as the main pass element in a high-current OR-ing MOSFET or hot-swap controller. The low RDS(on) minimizes forward-conduction losses that would otherwise degrade the efficiency of redundant -48V supply rails. The kelvin-source pin simplifies the gate-drive design for the fast turn-off required during reverse-current fault conditions, while the AEC-Q101 screening provides additional reliability margin for always-on telecom infrastructure.
Recommended
Solar String Inverter High-Side Switch
In transformerless solar string inverters with 80-100V maximum input voltage per string, the IAUA210N10S5N024AUMA1 serves as the high-side disconnect or active clamp switch. The 100V VDS rating handles open-circuit string voltage with margin, while the 2.4 mΩ RDS(on) minimizes steady-state losses during normal operation. The PG-HSOF-5-4 (sTOLL) package allows a compact power-stage PCB layout that simplifies the inverter's mechanical design. AEC-Q101 qualification, while not strictly required for solar, provides additional reliability margin in outdoor installations subject to wide temperature cycling.

Design Notes
Estimated: at TC=25°C, the IAUA210N10S5N024AUMA1 can dissipate 238W, but in a typical PCB application with 4-layer FR4 and 2 oz copper on top/bottom layers, the effective θJA is approximately 35-40°C/W. At 100W continuous dissipation, this implies a junction-to-ambient temperature rise of 100-130°C, requiring either a smaller continuous current or a forced-air heatsink mounted to the exposed drain pad. Designers should consult the Infineon application note on thermal design for sTOLL and verify with a thermal simulation tool before finalizing layout.
The PG-HSOF-5-4 (sTOLL) package's kelvin-source pin (SK) MUST be connected directly to the gate-driver output ground return, NOT to the main power-source path. This separation reduces the source-inductance L × dI/dt voltage spike that otherwise opposes the gate-drive signal during switching transitions. Place input capacitors as close as physically possible to the drain and source pads to minimize high-current loop inductance; a 1-2 oz copper pour spanning at least 1 square inch on the drain pad is recommended for the thermal path.
Do not use a 60V-class drop-in alternative (e.g., IAUC120N06S5L015ATMA1 or ISC015N06NM5ATMA1) in a 48V automotive application without verifying the maximum transient VDS under all load-dump conditions per ISO 7637-2. The 60V parts have insufficient margin for worst-case transients on a 48V bus. Also, avoid paralleling this MOSFET with a smaller sTOLL part on the same gate-drive circuit unless the gate resistors are individually tuned - the matched Qg and threshold of identical parts is essential for current sharing.
Recommended PCB footprint: use the Infineon-recommended land pattern from the package drawing in the datasheet. The drain pad (large exposed thermal pad) should have thermal vias in a 4×4 array, 0.3mm diameter, plated and filled to maximize heat transfer to inner copper planes. Solder paste stencil: 100-125 µm thickness for the drain pad to ensure proper voiding control (target <10% voiding per IPC-7530). Lead-free reflow profile per JEDEC J-STD-020 is mandatory for the AEC-Q101 qualified parts.
